The substation UWB positioning personnel location management solution developed by 95power relies on the powerful ultra-wideband UWB positioning technology of 95power, through the installation of UWB positioning base stations in the substation personnel activity area, and the staff wear UWB positioning tags (Such as UWB positioning card or bracelet), you can view the real-time position of the staff at any time in the background, provide convenient and fast high-precision positioning technical support for the safety management of substation personnel, and assist in the standardized and information construction of substations.
The substation UWB positioning personnel safety management system consists of: display terminal, UWB positioning engine, UWB positioning tag, UWB positioning base station.
(1) Display terminal: The positioning label coordinates calculated by the UWB positioning engine must be displayed on the display terminal (PC, tablet, mobile phone).
(2) UWB positioning engine: The UWB positioning base station in the substation positioning area sends the original position data to the UWB positioning engine through the network in real time, and then the UWB positioning engine runs the positioning algorithm to calculate the coordinate position of the person wearing the UWB positioning tag in real time.
(3) UWB positioning tags: UWB positioning tags are provided on the personnel and equipment to be located, and the positioning tags emit UWB signals and communicate with the UWB positioning base station so that the tags themselves can be located. The UWB location tag can be a wristband type, a work card type, or a module type fixed on a helmet.
(4) UWB positioning base station: UWB positioning base station communicates with positioning tags through UWB signals, and then through the back-end server-side positioning engine to solve, realize the precise positioning function of UWB positioning tags.
According to the design of the UWB positioning system architecture, the connection, data interaction, business processing, etc. between the various functional subsystems are implemented and managed by the interface subsystem. The main interfaces are as follows, as shown in the figure below:
(1) API interface of positioning engine data
(2) Docking interface with sound and light alarm
(3) Docking interface with monitoring display
(4) Docking interface with alarm subsystem
(5) Interface with surveillance video
The UWB positioning base station is deployed in the substation personnel activity area, and the real-time distribution of the positioned staff can be checked at any time by the display terminal in the background, so as to solve the problem of real-time monitoring.
(2) Staff dynamic roll call, statistics, management, etc.
The operation and management personnel of the substation can view the current number of people who should arrive, the actual number of people, the number of missing people, and those who have not arrived on the terminal.
(3) Staff movement track storage and playback
The historical movement trajectory of the positioned person can be viewed through the UWB positioning system, every detail can be traced, accountability can be based on evidence, and abnormal movement trajectories can also be analyzed.
(4) Deploy electronic fences in hazardous areas
An electronic fence can be set up in the dangerous area of the substation to monitor the entry and exit of people in this area.
(5) One-click for help in dangerous situations
(6) Alarm function
Including real-time early warning, various types of early warning (SOS, low power, offline, stay overtime, fence), early warning data recording and analysis, etc.
